2.1Middleeardiseaseclassification
The middle ear infection is characterized by Traumatic perforation, Otitis media
with effusion (OME), Congenital cholesteatoma (CC), Congenital cholesteatoma (COM),
Acute otitis media (AOM) [2].
Perforation due to trauma is a type of otitis media that can cause pain, bleeding,
hearing loss, tinnitus, and dizziness, something is inserted into the middle ear,
explosion, slap, head trauma, sudden decompression, air pressure disorder, etc.
Perforation in which organs inside the middle ear are visible and bleeding caused by
this perforation are diagnosed through an otoscope [3].
Exudative otitis media refers to middle ear infections caused by bacterial or viral
infections and its characterized by exudate. OME occurs frequently in infants and
young children, and the eardrum expands due to the exudate, or increase in pressure
in the eardrum, resulting in a hole in the eardrum, and exudate flows through it [4].
Congenital ear abnormalities mean no ears, are not formed, or incompletely
developed at the time of childbirth, such as hearing impairment due to lack of
eardrums and absence of external earring, etc. In this paper, only less eardrum
formation was considered [5].
COM means purulent otitis media, traumatic perforation lasting more than 6
weeks. This type of otitis media includes non-painful otorrhea and conductive hearing
impairment, and includes other infections such as polyps and limbs. In this case, a
diagnosis using CT and MRI is required to observe and diagnose otorrhea [6].
AOM refers to the case of sudden inflammation in the eardrum, and rapid cycles
of pain, fever, and fluid occur. In infants and toddlers, there are reactions such as crying,
irritability, lack of sleep, and reluctance to care appear. In this case, the eardrum
